Destination & City Travel Guide
About London
London works best when visits are grouped by area. The British Museum and Bloomsbury can fill one half day, while Westminster and the South Bank offer a different walk along the Thames. Borough Market is close to several river sights, and Greenwich deserves its own trip. From Heathrow, the Elizabeth line, Underground and express rail service reach different parts of the city, so the useful transfer depends on the hotel rather than simply on speed to Paddington.
Read more about London
What's new in London
May 2025: V&A East Storehouse opened in Queen Elizabeth Olympic Park, allowing visitors to explore museum collections in a working storage setting.
April 2026: V&A East Museum opened nearby, adding another art and design destination to an east London visit.
Tips for travellers from India
Paddington is convenient for Heathrow Express arrivals, but the Elizabeth line can be more useful for a hotel near Tottenham Court Road or farther east. Bloomsbury suits the British Museum and central walks; South Kensington suits the museum quarter. Compare the final station rather than only the advertised airport-train duration. Heathrow’s Piccadilly line takes another route through west London and can avoid a change for some addresses.
Air India uses Terminal 2, while British Airways operates from Terminals 3 and 5. An airline name alone therefore does not always identify the correct building. Within London, use the same contactless card or Oyster card when entering and leaving a rail service. Greenwich is a separate outing along the Thames, not a quick extension of a Westminster museum day. The V&A East sites are in the Olympic Park and should not be confused with the original V&A in South Kensington. Pair the east London museums with one another instead of crossing the city between their entrances.
Best time to visit London
May to September, commonly about 11–24°C, for longer daylight and outdoor walks.
